RAILWAY-DUMP.

Application filed. May 7, 1917. Serial No. 167,054..

To all whom it may concern Be it known that I, ALEXANDER H. WOOD, a citizen of the United States, residin Kildav, in the county of Harlan and tate of Kentucky, have invented a new and useful Improvement in Railway-Dumps, of which the following is a specification, reference being had to the accompanymg drawi Iy improvement relates particularly to railway dumps which receive loaded cars upon one track and discharge said cars, when empty, from the same end of the dump and upon another track, the movement of the cars toward and from the dump being usually by gravity.

The object of the invention is to provlde an eflicient dumping structure by means of which loaded cars may quickly enter the dump, discharge their loads, and move out upon the discharge or return track.

In the accompanying drawlngs,

Figure l is a plan of a structure embodying my improvement; 7

Fig. 2 is a sectional side elevation of the same structure;

Fig. 3 is a section on the line, 33, of Fig. 2, looking toward the right; 3

Fig. 4 is a section on the line, 33, of Fig. 2, looking toward the left;

Fig. 5 is a section on the line, 5-5, of Figs. 1 and 2 looking toward the left;

Fig. 6 illustrates locking mechanism;

Fig. 7 is a detail view of the driving mech anism for rotating the cylindrical frame.

Referring to said drawings, A is an understructure such as is ordinarily used for supporting car dumping mechanism, except ing that in the present case this understructure is modified to meet specific require ments. On the understructure is an approximately horizontal platform, B, hinged on a horizontal axis at B at its left hand or closed end. The right hand or open end of the platform is suspended by a cable, C. At each side of the platform one end of said cable is attached to the platform by a securing member, G which is attached to the platform. From said member, C the cable extendsupward over two pulleys, G on a rotary shaft, G which is horizontal and transverse to the length of the platform. Thence the cable extends downward below the platform and over stationary, grooved guide pulleys,.C*, and beneath a grooved pulley, G which supports a U-shape hanger, C, to which is coupled a counter-weight, W. The pulley, C rests on the downwardextended portion of the cable and transmits power through the cable to the platform,

on the platform. I a f At each side of the free end of the platform, a stop member, A supported b or forming a part of the underframing, is in position to extend over a portion of the platform when the latter is in its upper position. This limits the upward movement of the platform. Below each stop member, A is a similar stop member,-A at the proper elevation to arrest the downward movement of the platform when the desired limit of downward movement has been reached. a 1

As will be described fartherron, the counter-weight operates to normally move the free end of the platform into its upper positlon.

On the platform, B, are wheels, F, arranged with their axes on two lineswhich are parallel to each other and to the length of the platform, and said wheels are supported upon bearings, F Said wheels make supports for a tubular cylindrical frame, G, formed of longitudinal bars, G and transverse rings, G the latter resting on the wheels, F. WVithin said tubular frame are longitudinal track rails, G which are whereby the cable constantly pulls upward Specification of Letters Patent. Patented Dec. 16, 1919. V

adapted to register with the rails of the track, D, when the platform, B, is in alinement with that track and to register with the rails of the track, D when the platform is in alinement with that track. Above the rails, G are upper rails, G which are above the path of the Wheels, H of the car, H. Said four rails are adapted to hold the car during the rotation of the tubular frame, G, for inverting the car to discharge its contents by gravity. For further details concerning such a rotary tubular dumping frame, reference is made to Letters Patent of the United States, No. 1,204,527, granted to me November l, 1916. The mechanism for rotating said tubular framemay be of .any suitable form. For this purpose, the

tinuous shaft, F and an electric motor, I,

mounted upon the platform, B, and connected with said shaft by gears 1 1 I and I (Fig. '2'

On the understructure, and at the right of the platform, B, a track, D, inclines toward the platform and registers with the track rails, G in the cylindrical frame, G, when the platform, B, is in its upper position. Below the track, D, is a track D inclined away from the platform and at the proper elevation to register with the track rails, G when the platform is in its lower position.

6n the structure, A, at the pivot end of the platform is. a buffer, J, of any suitable form and standing high enough to be en gaged by cars which tend to move through the tubular frame, G.

At each side of the free end of the platform, B, is a laterally-directed stud, B On the understructure, A, at each side of the space occupied by the platform when in the upper position is a hook, A hinged at A5, in position to engage the ad acent stud, B when the platform is in its upper position, the free end of the hook being extended downward and the hook having a cam face, A normally extending into the path of the stud, B so that when the platform. is moved upward, the stud will push the hook aside until the stud is above the shoulder, A, whereupon the hook will swing by gravity to bring said shoulder beneath the stud. A rope or wire, A, is applied to the hook to be used by an attendant for drawing thehoek out of engagement with the stud when the platform is to be lowered. At each'side of the space oceupied by the platform when the latter is in the lower position, a gravity stop, A is hinged at A and has a cam face, A and a shoulder, A in the path of the stud, B lVhen the platform moves into its lower position, the stud, B bears against the cam face, A, and pushes the stop aside until the stud is below the shoulder, A whereupon the stop member swings by gravity toward the platform, the shoulder, A extending into the path of the stud and preventing upward movement of the latter and the platform. A cord, chain or wire, A attached to the stop member is to be used by an attendant for drawing the stop memher out of engagement when it is desired to release the platform for upward movement. The counterweight is to be sufficient to lift the platform with the empty tubular frame from the lower position into the upper position, but not suiiicient to hold the platform (when unlocked) in the upper position when a car or several cars, either empty or loaded, are on the platform. 7

'When the platform is in the upper position and locked, and the tubular frame is so turned as to bring its traek rails to the lower position, one or several loaded cars are moved over the track, D, into said frame. Suitable blocking is then applied to the cars to prevent them from moving endwise. The tubular frame may now e rotated for dumping the loads out of the cars, this being done by transmitting power from the motor, I, to the shaft, F or the dumping may be postponed until the platform is in the lower position. To change the platform to the lower position, the hooks, A are released, whereupon the preponderatin aggregate weight of the platform, the tu ular frame, and the cars overcomes the counterweight, and the latter rises and the platform descends until it is stopped'by the stop members, A'-, and locked by the stop mem bers, A Then the cylindrical frame is rotated for dumping, if that was not done when the platform was in the upper position. Then the cars are released and allowed to run by gravity out of the tubular frame and over the lower or discharge track, D

Then the attendant releases the stop members, A whereupon the counter-weight draws the platform to its upper limit, the hook, A engaging the studs, B automatically. d

On the shaft, C is a drive wheel, which may receive power for driving said wheel and said shaft in the proper direction to supplement or oppose the action of the counter-weight.

A brake lever, C is pivoted at C and adapted to bear by one end against a brake wheel, C on a shaft, C A cord, C, depends from the free end of said lever and may be engaged by an attendant and drawn downward to cause the opposite end of said lever to bear against said brake wheel to re strain the upward movement of the platform in response to the action of the counterweight or to restrain the downward movement of the platform when it supports the loaded cars.
